VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent N o. 380,169, dated March 27, 1888. I

Application filed December 2, 1887. Serial No. 256,749. (No model.)

To all whom t may concern.:

Beit known that I, CHARLES M. BLYDEN BURGH, a citizen of the United States, residing at Riverhead, (Long Island,) inthe county of Suffolk and State of New York, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a side elevation of one of my improved springs. Fig. 2 is a bottom plan view of the same. Fig. 3 is an enlarged detail of the central portion of the springs, showing the manner of crossing the springs.

My invention relates to springs supported upon the front and rear axles of a Vehicle; and it consists in the improved spring hereinafter fully described and specifically claimed.

To enable others skilled in the art to which my invention appertains to. make and use the same, I will now describe its construction and indicate the manner in which the same is carried out.

In the said drawings, A A represent semielliptical or curved springs secured at opposite ends by shackles a to the bars B. These bars sustain the springs and cross the axle, said bars being secured to the axle by any appropriate means, and they may be made of wood or iron, or when extra softness is wanted I sometimes employ ordinary leaf-springs in place of the bars. v

. From their points of connection with the bars the springs A A extend diagonally from one bar to another, crossing each other at the center, as shown in Fig. 2, Aand each spring comprises two plates or leaves, b b, having straight or iiat central portions, c c', said iat portion on the upper leaf, b, of each spring being not so long as the corresponding portion of the vother leaf, b, whereby a spacev is left between the contiguousfaces of the plates or leaves b b for the introduction of suitable pillars, d, which are placed upon each side of the central pivot-bolt. This construction also permits the central portions of the leaves of one spring A to pass between the corresponding portions of the leaves of the other spring without necessitating the cutting away of any part of either spring, thus retaining their full strength.

To the top of the central portions of the A A in the center without cutting the plates or having them fit imperfectly. This is readily accomplished by making the central portions of the springs about straight, the straight part of each successive leaf or plate being Y somewhat shorter than the one over-which it fits, thereby making it possible to fit the leaves of each spring closely together except at the center or fiat portion.'

I am enabled by the above construction to dispense with the reach when a platform spring-wagon is to befmade. If a light vehicle is to bek constructed, I draw the ends of the crossed springs closer together and pivot or couple them toa short bar, and then put in the ordinary reach king-pin, &c., to keep the axles from drawing out of place and the springs from'cantingforward.

The construction before stated will not rock or roll forward and backward when used on rough roads, as do those gears which have but one spring placed lengthwise of the axle. The

same is also true when two parallel springsv are placed close to either side of the axle.

When my invention is applied to a platformgear and the ordinary reach dispensed with, I can use an ordinary short ve-foot orflvefoot-six-inch body, whereas in the ordinary platform-gears this cannot be done unless long bars (bodyloops 7) project out back of the body for the back cross-spring to rest against.

These are only a few of the advantages to be gained by the use of my invention, which is applicable to any style of wagon-gear havingV either straight, curved, or cranked axles.

Single-plate (such as lribbed steel) springs may be used instead` of plural plates whenV lightness of weight is important.

Having thus described my invention,what I claim as new, and desire to secure by Lettersl Patent, is

1. The curved springs A A, secured to the bars B and extending along the axle diag- IOO onally from one bar to another, said springs comprising a plural number of leaves or plates having flat central portions of unequal lengths, forming a space between said leaves, whereby 5 the leaves or plates of each spring pass between and cross the leaves or plates of the contiguous spring, substantially as described. 2. The springs having lower leaves or plates, b', with'at central portions, and the 1o4 upper leaves or plates, b, fitted to the lower leaves, having dat central portions shorter than the dat portions of the lower leaves, whereby a space is left between the central portion of each contiguous leaf, in combination with the bars B, to which the ends of the springs are secured, and the pillar plates or washers in said spaces upon each side of the central pivot-bolt, substantially as described.
